.Beit kinown that ."I, Jonnhlannnn, -a citizeny of the UnitedA States,residing at, lIrvington,.in the county-.,oEsseX Aand State of NewJersey, have..invented.cer.tain new .and .useful ImprovementsinPyrometers orfThenmo-B atteries; and .I do' hereby declare the.iollowing. toA bexa full, clear,and exact description ,of theinvention,such as will enable lothers skilled th'e art to whichit appertains tomake zand use the same, reference being had. to the accompanyingdrawings, and. to characters of. reference marked thereon, .whichorm .a.part of this specication.

.The present invention has referencegen eralbly, to .a .novel .and.simply constructed devlce orapparatus in the form Aof a pyrometer.

general character -hereiua couple, .adapted to be resent invention hasfor its principal ob]e'ctx to provide an a paratus of the er tmoreVfully specified, in the form of a simply constructedand eiicientheat-collector andthermoarranged in electric circuit with agalvanometer, and bymeans of which the current induced by the various.degrees oitemperature ,and` caused by thecollected heatmays within saidcollector may lbe made to -produce corresponding movements of theenergizing -coil and the index-hand of. a. galvanometer.

:Other objects ofthis inventionnot at this time more particularlyenumerated willbe .clearly understood, from. the following de- -Fig is atransverse vertical section,

- which :is suitably sentation of a heatcollector showing one embodimentof the, principles of the present invention;F ig. 2 is 1.a longitudinalvertical section ofthe same, taken centrally throughthe.heatcollecting.tube of the device; and taken online 3 3 in said.Fig.2, looking in the .direction of the .arrow said View being made Aantanenlarged scale. Fig. 4 is a detail-'longitudinal vertical section, on anenlarged-scale, said section being taken on line bottom-.view of .abase-plate upon w ich the heat collecti-.ugtube .is adapted to besecured: and'Fig. 6. is a face view of the heatray. collectingend-portion of the heat-collectingx tube, provided witha removablereducing shutter or. slide.

f Similar characters. of v reference. are employed in .all vof theabove. described views, to` indicate. corresponding parts.

-Referringnow to Figui of theV drawings, there-areshown herein twocircuit-wires, 6o

rand 66, which are suitably .attached to the binding-posts v67 and 68 ofa base 69.1nade from suitable insulating material, and upon mounted theherein-before mentioned heatrays collector. This collector consists,essentially, of a tubular body 70, secured at its one end-portion uponsaid base 69, by means of screws 71 and 7 one end of.. the sald body ZObeing left. open, as

.at 7.3, while its other end is closed, preferably byfmeans cfa disk 7imade of suitable insulating material. Vithin the said tubular. body 70,at a pointY near its closed end, is .a thermo couple. This thermo coupleconsists, essentially, .of post 7 5' made from suitable insulatingmaterial which is surrounded'by a chambered or tubular casing 76,. alsoof suitable insulating material, the lower portions ,of said postl7 5and the casing 76l extending through an opening 77 in said tubular.body.'0" and being secured to the base .67 byf means of a screw 78, orother suitable fastening. means. `Suitably riveted upon the oppositesides of saidlpost 7 5', or Aotherwise secured thereto, arecontact-mak,- ing metal .plateflike members 79 and SO with which. 'sconnected a frame-like met-al member or element, as 81, which is formedwith suitably shaped and angularly disposed heat-ray collecting ritilesor projections, as 82, which are preferably struck' "up" out of themetal of which the member or element 81 is made. Connected with thebinding post 67, and suitably secured `thereto by means of a bindingscrew 83, is a circuitwire 84 which passes through aperforation or hole85 in the basek 69 and i'nto and through the chambered.' or tubularcasing 76, said wire leading out therefrom and being suitably connectedwith the plate-like member 79. In like manner,` there is conlected withthe bindingv post 68, and Asuitably secured thereto by means of abinding screw 86, a circuit-wire 87 which passes through a perforationor hole 88 in the base 69 and into and through the chambered or tubularcasing 76, said wire leading out therefrom and being suitably vconnectedwith the plate-like member 80. In this manner, the thermo-couple may beproperly arranged in circuit with a galvanometer, as

will be clearly evident; and, whereby the heat-rays which are collectedby the rillies 82 will produce'an electric current in the completedcircuit, and said current will be conveyed to the galvanometer. Back ofthel saidrthermo-couple' is a concave mirrorv89, Iliade of silver, orany other seuitablematerial of greatradlatmg efficiency, said mirrorhaving suitably secured upon its back,

by means of solder 90, or other suitable fastenxing means, a member 91which is provided with an upwardly extending screwthreaded shank 492.?.lThis shank 92 Lextends through a slide, such as 93, which is suitablyitted in and is slidably arranged in the tubular body 70, the upperscrew threaded end-portion of s id shank 92 through a slot 9 in the saidtubular-body 70 and having arranged thereon a binding or tighteningV nutor ingerpiece-95. The said slide 93 1s also provided with a guidingstud,as 96, which extends upwardly and is slidably disposed inrjsaid slot 94,so as to retain the slide in"` its proper sliding relation, and toproperly retain the mirror in its position for receiving the rays ofheat and by reflection focusing said rays upon the collecting riiilesofthe thermo-couple. This arrangement of these several parts alsopermits of an adjustment of the mirror, back and forth, to a certaindegree within the tubular body 70, as will be clearly evident. The saidtubular body 70 is also provided at its.. open end-portion 'withforwardly extendingfarms or rods, as 9T, which carry upon ltheir freeends Va perforated shield, as 98, through which the heat-rays' areprojected into said tubular body for distribution uponV the mirror fromwhich the rays are reliected directly upon the rilles of thethermo-couple. Within the said tubular body 70 there may also be aralsoextendingjv f rangedii'al ring-shaped device or perforated shield 499.which Aprevent-s anyfaflse :currents Vof air from. radiating upon] thethermocouple. If desired, the opening in the sliield 98 maybe madesmaller b the arrangement over saidv shield of a suitable shutter 100which is provided with a reducing opening 101, the said shutter beingprovided with a iingerpiece 102, and being removably arranged uponsaidshield 98 by an Varrangement of fingers, as 103, with which the saidshield may be provided. Of course .it will be understood that anysuitable tornir of reducing shutter maybe employed, and' any othersuitable means ma be used with the saidshield and shutter or connectingsaid shutter with said shield. f I The "workings and operations of theseveral parts of the apparatus willbe clearly understood from theforegoing descriptiony and from. aninspecton of the severaly Ifigures ofthe dra-wings, and need, therefore, not be further described.
